One of the modifications in the Doc patch about Tools->Reload Configuration is in the *Inserting Unicode characters* section. Here is the modified excerpt:
With GTK 2.10 and above, you can insert Unicode code points by hitting
Ctrl-Shift-u, then still holding Ctrl-Shift, type some hex digits representing the code point for the character you want, then let go of Ctrl-Shift and hit Enter or Return.
For this to work in Geany, you'll need to first unbind Ctrl-Shift-u in the `keybinding preferences`_, then select *Tools->Reload Configuration*
or restart Geany. Note that it works slightly differently from other GTK applications, in that you'll need to continue to hold down the Ctrl and Shift keys while typing the code point hex digits.
I tried this when checking for Reload Configuration effects. I noted that currently (revision 4675) Ctrl-Shift-u is not bound in the *keybinding preferences*, and that using Enter or Return to end the Unicode specifier actually entered a carriage return in the text. Intuitively, a space after the code should be enough to end the specifier, and indeed it does. I'm not sure whether this is a bug in the code, or a needed document modification. I didn't go looking for the point in revision history where the behavior changed.
